PostgreSQL Integration
Data & Integrations

It would be good to provide native support for PostgreSQL

Or MySQL. I prefer PostgrSQL, but MySQL has a much wider userbase. I just want to see support for a free/open source DB to help bring the total cost of ownership down.

I want to see outsystems kill their own custom built ORM and replace it with open source hibernate 
Doing this will allow Outsystems customer to decide which database they want to use, rather than be given only two choices SQL Server or Oracle!

Hibernate/nHiberate is built for JAVA and .NET, it supports the following databases.

RDBMS Dialect
MySQL5 org.hibernate.dialect.MySQL5Dialect
MySQL5 with InnoDB org.hibernate.dialect.MySQL5InnoDBDialect
MySQL with MyISAM org.hibernate.dialect.MySQLMyISAMDialect
Oracle (any version) org.hibernate.dialect.OracleDialect
Oracle 9i org.hibernate.dialect.Oracle9iDialect
Oracle 10g org.hibernate.dialect.Oracle10gDialect
Oracle 11g org.hibernate.dialect.Oracle10gDialect
DB2 org.hibernate.dialect.DB2Dialect
DB2 AS/400 org.hibernate.dialect.DB2400Dialect
DB2 OS390 org.hibernate.dialect.DB2390Dialect
PostgreSQL org.hibernate.dialect.PostgreSQLDialect
Microsoft SQL Server 2000 org.hibernate.dialect.SQLServerDialect
Microsoft SQL Server 2005 org.hibernate.dialect.SQLServer2005Dialect
Microsoft SQL Server 2008 org.hibernate.dialect.SQLServer2008Dialect
SAP DB org.hibernate.dialect.SAPDBDialect
Informix org.hibernate.dialect.InformixDialect
HypersonicSQL org.hibernate.dialect.HSQLDialect
H2 Database org.hibernate.dialect.H2Dialect
Ingres org.hibernate.dialect.IngresDialect
Progress org.hibernate.dialect.ProgressDialect
Mckoi SQL org.hibernate.dialect.MckoiDialect
Interbase org.hibernate.dialect.InterbaseDialect
Pointbase org.hibernate.dialect.PointbaseDialect
FrontBase org.hibernate.dialect.FrontbaseDialect
Firebird org.hibernate.dialect.FirebirdDialect
Sybase org.hibernate.dialect.SybaseASE15Dialect
Sybase Anywhere org.hibernate.dialect.SybaseAnywhereDialect

Outsystems - Why should you do it?
Firstly hibernate is open source and free, it is used by many top developers and vendors such as IBM, hiberate has been tested on a large scale.

It will save you time and money, why continue to burn time and money maintaining your own custom ORM which only supports SQL Server and Orcale, then when a new version comes out you have to continue to burn time and money to support new features - how does this make sense?

If you were selling a ORM product, ok this makes sense, but your not selling an ORM product.

If you wanted a charting feature and you went your own charting tool, rather than use highcharts, I would ask you the same questions, why are you losing your time and money? how does this benefit your company in the long term? how does it benefit your customers? 
I'm probably very stressed today :)

Using the available SDK, I have created a connector for PostgreSQL so I guess this idea is covered :)

As for platform database, that's another story :)

We have provided a Database Integration SDK that allows creating connectors to other database systems that don't come out of the box with OutSystems. Because not all customers have the capacity to create such connectors we provide this SDK in a Limited Availability program.

Using this SDK some of our customers have already built connectors to other database systems namely PostgreSQL as Ricardo Silva has mentioned in this thread.
